Answer:
8 and 1 third.
Step-by-step explanation:
The answer would be c) 129
Equation of a line is given by y - y1 = m(x - x1); where m is the slope.
y - 4 = 2/5 (x - (-2))
y - 4 = 2/5 (x + 2)
We are simplifying this so they are easier to add in your head.
87+33 is easier math to do in your head
so our new estimated number would be 120
(8,9)
To find the midpoint of coordinates is adding all the X axis coordinates and dividing it by 2 (9+7 divided by 2=8)
Same goes for the Y axis (5+13 divided by 2= 9)
